FusionCore is an emerging cybercrime group that transitioned from solely developing stealers in early 2022 to operating a Malware-as-a-Service (MaaS) platform and providing hacker-for-hire services. The group is assessed with medium confidence to originate from Europe. Their primary motivation is financial gain through the sale of malware subscriptions and the execution of customized cyberattacks for clients. FusionCore distinguishes itself by functioning as both prolific malware developers and service providers, offering a comprehensive suite of proprietary malware, often named after Greek mythological creatures, and providing detailed instructions to enable even less experienced threat actors to conduct complex operations.
